Abstract

Abstract

A self-regulating multiple layers combined floating-island was used for water purification of the Xihe River, and the purification effect of plant species and flow rate on COD_Cr and NH₄⁺-N studied. The results showed that the floating-island planted with canna and reed had the highest purification effect of COD_Cr(75.30%) and NH₄⁺-N (75.76%) respectively for the simulated river water. The optimal flow rate was 0.75 L/h. The purification effect of multiple layers combined floating-island on the Xihe River was good and the purification effect of floating-island for both COD_Cr and NH₄⁺-N could achieve 50% or so.
